SS-31 (elamipretide) is a mitochondria-targeting peptide that binds cardiolipin on the inner mitochondrial membrane, helping stabilize the structures responsible for cellular energy production. By restoring mitochondrial efficiency, SS-31 supports recovery, endurance, and healthy aging while reducing the oxidative stress that drives age-related decline in muscle, heart, kidney, and neurological tissue. SS-31 can help your cells resist the effects of aging by: Restoring mitochondrial structure and function, Improving ATP production and cellular energy output, Reducing oxidative stress and free radical damage, Supporting muscle strength, endurance and exercise recovery and Protecting tissue from age- and stress-related damage.
